convert an int to string

Question

I'm trying to create an object by converting an 'int' to a 'String'. I'm working on an ADT stack program but I was asked to use data type String.

*I was able to figure out:

int top = -1;
String stkTop = Integer.toString(top);

*But how do I create this int to String?

int[] data;
data = new int[10];

What is in your `data` array? You want to concatenate 10 integers into a single String? Like '1234567890'? — milosmns, Oct 27 '16 at 20:59
What does ADT stack mean? the `adt` tag here means "Android Development Tools" — OneCricketeer, Oct 27 '16 at 21:01
Can't you just loop through the array and add them one by one into a StringBuilder structure for example? Otherwise, there is a constructor to create a String from a byte array - but it's `byte`, not `int`.

Your question contains no `Stack` objects or `abstract` references, though... — OneCricketeer, Oct 27 '16 at 21:07

You can use Arrays.toString() to accomplish this

String stkTop = Arrays.toString(data);

What about `Arrays.toString(data)`? – OneCricketeer Oct 27 '16 at 21:05
Why the detour? You can simply use `Arrays.toString(data)` – QBrute Oct 27 '16 at 21:06
Arrays.toString(data) returns with the brackets "[0,1,2,3,4,5,6,7,8,9,10]" if he doesnt need he would probably have to substring the result. – Eddie Martinez Oct 27 '16 at 21:37
@EduardoDennis `Arrays.asList(data).toString()` yields the exact same output. – QBrute Oct 27 '16 at 21:43

Once you have the values for the array you can just do a simple for loop.

int[] data = {1,2,3,4,5,6,7,8,9,10};
String numbers = "";

for(int x=0; x<data.length; x++){
    numbers = numbers + data[x] + " ";
}

You can do something like this:

public String intArrayToString(int[] in){

    Stringbuilder sb = new StringBuilder();

    for (int x : data) 
            sb.append(x);

    return sb;
}
